Delt inj AM and pain/pinch while pressing PM

I pinned 2.5 ml IM delt AM, then went to the gym about 12 hours later. Activated rotator cuffs, and did some pre bench work, and a few warmups. Rep 3 on a first working set, nothing heavy and I feel a sharp pinch feeling. I racked it.. then threw on 135 x 1 slow rep to just assess. Painful again not as much. Skipped the rest of direct chest work, trainee triceps good and quick upper back (chest supported row) with no pain.

Anyone had this happen as a direct relation of inflammation or scar...
